When secondary loop in power system carries out service work, in order to prevent service work from causing shadow to other operation equipment
Ring, need to disconnect secondary circuit.Disconnecting secondary circuit is to pull down secondary line cable the end of a thread in terminal block mostly.Due to portion
In two times line cable the end of a thread be live wire it is however generally that, secondary line cable the end of a thread that these remove be required for doing insulate every
From process.Although part secondary line cable the end of a thread is not charged, once encountering electrical body can cause adverse consequences.Therefore, by this
It is most important that the secondary line cable the end of a thread removing a bit carries out insulation processing.Additionally, for complicated working site, may have many
Individual loop needs to do insulation measures.
At present, conventional insulating treatment method be with insulating tape be wrapped on cable the end of a thread will cable the end of a thread exposed
Metal core is wrapped, and so can prevent people or other equipment is encountered and caused personal injury or electric network fault.
There is following problem in above-mentioned insulating treatment method：
First, it is wound around insulating tape and cause defective insulation because of due to staff's technical merit or sense of responsibility, no
Real insulating effect can be played.
2nd, during with insulating tape parcel live wire, human body is made to touch because of careless manipulation powered
Body, causes personal injury.
3rd, Reusability insulating tape parcel live electric cable the end of a thread, easily leaves filth on metal core, leads to metal
Core connects reliability decrease when reusing, and may result in loop connection bad when serious.
4th, insulating tape uses rear not reproducible use, and every task will waste more with new insulating tape.
5th, operating efficiency is relatively low in this way, needs to spend the more time.
6th, when there being multiple loops to need to do insulation processing, because of place dispersion, process points are many, lead to finally extensive
Easily occur when multiple omitting, and then lead to a disaster.
Content of the invention
The present invention is intended to provide a kind of cable head protection device, to solve the cable the end of a thread disassembling in prior art
The not good problem of insulation effect.
To achieve these goals, the invention provides a kind of cable head protection device, including：Insulation locking cylinder, absolutely
The two ends that edge locks cylinder are open end, are provided with locking inner conical surface in insulation locking cylinder；Insulation accommodation tube, insulation accommodation tube
First end be blind end, insulation accommodation tube the second end have with cable the end of a thread cooperation elastic portion, wherein, insulation locking cylinder and
Insulation accommodation tube is detachably connected, and when insulation locking cylinder and insulation accommodation tube connect, locking inner conical surface supports elastic portion makes elasticity
Portion is fixed on cable the end of a thread.
Further, it is threaded connection between insulation locking cylinder and insulation accommodation tube.
Further, insulation locking cylinder has shell of column and cone section, and the inner surface of cone section forms locking inner conical surface.
Further, elastic portion includes the circumferentially disposed multiple elastic card claws along insulation accommodation tube.
Further, elastic card claw is three, and the circumference of three elastic card claw edge insulation accommodation tubes is uniformly distributed.
Further, the cross sectional shape of elastic card claw is in arc-shaped.
Further, on the axis direction of insulation accommodation tube, through hole that the inner surface of multiple elastic card claws is limited
Aperture is gradually reduced from inside to outside.
Further, the material of insulation locking cylinder and insulation accommodation tube is plastics.
Application technical scheme, first insulation locking jacket casing is located on the cable the end of a thread disassembling, then will
Cable the end of a thread from be arranged on insulation accommodation tube second end elastic portion be inserted into insulation accommodation tube in, finally by insulation locking cylinder and
Insulation accommodation tube links together.It is provided with locking inner conical surface due in insulation locking cylinder, when insulation locking cylinder and insulation accommodate
When cylinder connects, locking inner conical surface supports elastic portion makes elastic portion be fixed on cable the end of a thread.Insulation locking cylinder so can be prevented
Split away off from cable the end of a thread with insulation accommodation tube, so, cable the end of a thread is contained in insulation accommodation tube, thus playing insulation
Effect, and then efficiently avoid the situation that operator touches and causes danger, safe and reliable.After use, insulation can be made to lock
Cylinder and insulation accommodation tube are separated from each other, easy to use, may be repeated use, cost-effective.Technical scheme is simultaneously
Also avoid because leading to the reliability decrease that cable the end of a thread is connected to connect bad problem with loop using insulating tape.
